Comments on "phase-shifting for nonseparable 2-D haar wavelets" [PDF]
, 2009 In their recent paper, Alnasser and Foroosh derive a wavelet-domain (in-band) method for phase-shifting of 2-D "nonseparable" Haar transform coefficients. Their approach is parametrical to the (a priori known) image translation.

Revisiting Leighton’s theorem with the Haar measure [PDF]
Mathematical Proceedings of the Cambridge Philosophical Society, 2020 AbstractLeighton’s graph covering theorem states that a pair of finite graphs with isomorphic universal covers have a common finite cover. We provide a new proof of Leighton’s theorem that allows generalisations; we prove the corresponding result for graphs with fins.

Advanced Science, EarlyView.A chlorine‐functionalized silane modifier (CPTMS) is introduced to cooperatively regulate CO2 reduction to C2+ products on Cu‐based catalysts. Dual‐functional interface sequentially enhances CO2 activation, intermediates protonation and C─C coupling, delivering a 5‐fold increase in C2+ faradaic efficiency (FE, 75% vs.

Frame Wavelet Sets and Wavelets in Banach Spaces [PDF]
Romanian Journal of Mathematics and Computer Science, 2014 In this paper, we try to study a special class of frame wavelets in Banach spaces whose Fourier transforms are supported by frame wavelet sets. Our results generalize the various results of [2] to Banach spaces other than Hilbert spaces using the ...

Sharpness of some Hardy-type inequalities
Journal of Inequalities and Applications, 2023 The current status concerning Hardy-type inequalities with sharp constants is presented and described in a unified convexity way. In particular, it is then natural to replace the Lebesgue measure dx with the Haar measure d x / x $dx/x$ .

Advanced Science, EarlyView.Biomineralization underpins skeletal development, yet its molecular control remains incompletely understood. Using a novel murine knockout model, this study reveals the essential and complementary roles of PHOSPHO1 and TNAP in postnatal skeletal development.

Products of K-Analytic Sets in Locally Compact Groups and Kuczma–Ger Classes
Axioms, 2022 We prove that for any K-analytic subsets A,B of a locally compact group X if the product AB has empty interior (and is meager) in X, then one of the sets A or B can be covered by countably many closed nowhere dense subsets (of Haar measure zero) in X ...

Advanced Intelligent Systems, EarlyView.Automatic left ventricular segmentation in echocardiography is critical for cardiac function assessment but remains challenging due to limited crossdomain feature interaction. This paper proposes SFMFNet, a Spatial‐Frequency Multi‐Scale Fusion Network that integrates multiscale convolution, wavelet transform, and Fourier transform.

A CONSTRUCTION OF A SYSTEM OF MEASURES SUPPORTED ON (r,d)-FIBRES OF A GROUPOID [PDF]
Fiabilitate şi Durabilitate, 2015 The purpose of this paper is to transfer the construction of the Haar measure of a locally compact group to the groupoid settings. The groupoid is endowed with a family of subsets containing the unit space.

International Journal of Mathematics and Mathematical Sciences, 1990 Let G be a compact Abelian group with character group X. Let S be a subset of X such that, for some real-valued homomorphism ψ on X, the set S⋂ψ−1(]−∞,ψ(χ)]) is finite for all χ in X.
